Amazon has the Season 3 DVD set of Happy Endings for $23.49. This is by far the lowest price anywhere and anytime as it rarely dips below $35-$40 for the set. That's over a period of 4 years.
This is because the DVD release is one of Sony's asinine "print on demand" titles, so there is never a need for a sale. Not sure why it is so low, but if you have been holding out on this, now's the time to buy.
If you're not familiar with the show, hilarious ensemble piece that never got it's due. You can check out Seasons 1 and 2 for the much more affordable price of $6-$8 each:
More info on "print on demand" from Amazon's site:
CD-Rs and DVD-Rs (the "R" stands for "recordable") look like the discs you're used to and offer the same audio and image quality. This recordable media is used to manufacture titles on demand, as fully authorized by the content provider.
Through manufacturing on demand, CreateSpace , part of the Amazon.com group of companies, enables Amazon.com to offer music and video content that might not otherwise be available. Each disc comes fully packaged, with artwork, in a standard jewel case for audio and an Amaray case for video, although for reissued products the artwork may differ from the original.
